Establishing a branch office of a UK corporate is also a possibility within Europe.
Basically, the UK (Main Office) corporate registers an office locally (Branch) by filing its constitutional documents translated (and certified) into the local language.
This type of set up is generally only advisable if it is driven by tax considerations. In our view the costs of setting up and the annual compliance burden more often than not do not outweigh setting up a proper subsidiary.
Another consideration is that the Main Office remains liable for the liabilities of the Branch.
